How do i find the minimum value of y??

Thank you!!

This does not have a minimum.

3. Well the full question waS differentiate y=-x^2+2x+3 which i did ^^
then find the mimimum value of y.
there is this underneath but i dnt think i needed it hehe
a gardener is considering a new design for his garden.he has a rectangle lAWN measuring 5m by 3m and wants to dig up part of it including a flower bed. he draws a plan of the lawn and flower bed on graph paper taking the bottom anf left hand edges as the axes and chooses the scale so that 1unit along each axis is representing 1m on the ground

So you meant $\frac{dy}{dx}=-2x+2$

It makes a bit more sense now but y still does not have a minimum value.

Do you know what the graph of $y=-x^2+2x+3$ looks like?

5. yes iv drawn the graph i actually need the maximum point. sorry
